Il2 was designed to use OpenGL, Nvidia's API. ATI cards now use an OpenGL wrapper, so you can use "perfect" settings in Il2, but as far as I know you are limited to "water=2", whereas with an Nvidia card you gain access to the "water=3" and "water=4" settings. The only problems I have with Nvidia are their drivers. It seems every new driver is geared towards performance in a specific game and may help new cards, but their backwards compatibility actually induces poor performance or instability with older cards and/or older games.

My Nvidia experience has been with a 6800 Ultra, 7950GT and now a 8800GT.
